commuter is twice as likely to select (#3) as to select either adjacent car
(#2 or #4), and is twice as likely to select either adjacent car as to select
either end car (#1 or #5). Determine the probabilities for selecting each
car.
A stock market analyst figures the probabilities that two related stocks, A and B, will go up in price. She finds the probability that A will go up to be 0.8 and the probability that both stocks will go up to be 0.3.

- There is a 30% chance that any current client of company A will switch to company B this year. There is a 20% chance that any client of company B will switch to company A this year. If these probabilities are stable over the years, and if company A has 1000 clients and company B has 1000 clients, in the long run (assuming the probabilities do not change), what will the market shares be?
